Abstract

The first generation of interferometric gravitational wave detectors performed one of the most precise differential length measurements ever. However, to measure the tiny length changes caused by a gravitational wave their sensitivity has to be increased even further. The technical upgrade of the Laser Interferometer Gravitational wave Observatory (LIGO) to a second generation detector, called Advanced LIGO, is currently under way. It will presumably reach a tenfold improved stram sensitivity between 10^-24Hz^-1/2 and 10^-23Hz^-1/2. One of the key technologies necessary to reach this precision is an ultra-stable high-power laser system.
